org.springframework.web.util.UriUtils

public abstract class UriUtils
extends java.lang.Object

Utility methods for URI encoding and decoding based on RFC 3986.

There are two types of encode methods:

• "encodeXyz" -- these encode a specific URI component (e.g. path, query) by percent encoding illegal characters, which includes non-US-ASCII characters, and also characters that are otherwise illegal within the given URI component type, as defined in RFC 3986. The effect of this method, with regards to encoding, is comparable to using the multi-argument constructor of URI.
• "encode" and "encodeUriVariables" -- these can be used to encode URI variable values by percent encoding all characters that are either illegal, or have any reserved meaning, anywhere within a URI.

Since:

3.0
